Specification forming al-t of Letters Patent No. 59,733, dated May 4,1869.

"To all whom it may comma York, have invented certain new and usefulImprovements in Droppers for Harvesters, of

which the following is a full, clear, and exact description, referencebeing had to the accompanying drawing,mak ing a part ofthis speci Figure1 is,aperspectiveofa'flrairvesting machineeinbracin g myfiinpro'vements,taken from the rear grainsideof the machine. a

I The novel features, of this application relate chiefly to theconstruction and arrangement of the'parts for operating thedroppingortilting platform and cut-ofl, and the other parts'of themachine, except so fari as theyarerequisi te to aproper understandingefsaidirnprovements,

need not therefore be described inidetailgj- My invention consists ihmountingarockshaft for operatin githe cropping; orj jdnmpin g platformin an adj ustable bracket or bearings n the single reelpjost,"andjalsollin mounting the cut-off or its actuating-arm inhearings on the adjustable reel-shaft bracket, so that the cut-off andreel shall be simultaneously ad justed in adapting them to tallorshortgrain,

' as will be hereinafter setforth.f

In the annexed drawing, A represents the Jnain frame, suspended on amain axle, B,

which is mounted on two independent driving and carrying wheels, 0 O,the inner one of which, 0, is represented broken away, in part, for thepurpose of showing other parts hereinafter described.

D is a seat and tongue plate or frame hinged to axle B E, the main shoe,pivoted at its rear end in a swiveling box, F, attached to the rear endof the frame A; G, a hinged brace or coupling, connecting the forwardend of shoe E flexibly with the front outer corner of frame A, andarranged in front of said frame. H is the finger-bar, connected wit-hshoe E at a form, which may also be made in any of usual well-knownforms, and is intended to be attached to and drawn forward by thefinger-bar. IL is an arching flanged standard, of irregular form, boltedor otherwise attached: to the main shoef E through flanges or feetll,ar-

ranged the one in front and the other behind the finger and cutter bars,in such manner as to cause the standard to stride said bars.

M isthe single reel-post, pivoted at its foot to standard L, and madeadjustable thereon ,for setting the reel forward or back, as thecharacter or condition of the grain may require.

N is an adjustable two armed bracket, in

bearings in the arms of which .ismounted the shaftof reel 0. Saidbracket or support Nis provided'with flangeso 0, which .embrace the postM, andrare connected atftheir outer edges by an eccentric, 0, bythe'rotation and aroperadjustment of which, by means ofhandie 0, thebracket "N may be clamped to and held at any desired height uponthereel-post "M, or loosenediolf adjustment thereon,as required.

ta point intermediate between standard LlandQreel-bearer N is asecondlbmcketor casting, 1?, also connected"adjustably to the Ireel-post, and provided with hearings, in which is mounted a rock-shaft,1), provided at its ends with vibrating crank-arms Q, Q, both of whichexpand in width as they recede from the shaft, and are provided eachwith a number of perforations, for a purpose hereinafter set forth. Theouter arm, Q, is connected by a rod or link, q, with a pivotedshoe-piece or treadle, R, arranged in convenient position to be operatedby the foot of the driver occupying seat D.

By varying the point of attachment of ,link or rod q with arm Q, throughthe perforations therein made for that purpose, the throw of shaft 2,when operated by treadle B, may be varied as required. The arm Q ofshaft 10 is intended to be connected, through adjustable link or rod gwith the dropping 0r dumping platform for operating the same. Byadjustin g the rod from one to another of the perforations in arm Q, theposition and extent of movement of the platformmay be varied to suit thecrop to be operated upon.

The reel-bearer or bracket N is armed with perforated lugs n n, in whichis mounted the swinging arm S of the separating-rod or cutoff S. The rodS and arm S may be made continuous or in one piece, bent in formsubstantially as shown; or the arm S may be provided with a sleeve, 8,in which the rod S may be inserted and secured in any proper manner. ArmS is provided, near its pivoted end, with an adjustable wrist or sleeve,8, to

- which one end of a rod, g is attached, the

other end of said rod being adjustably connected with arm Q ofrock-shaft p. The upper end of rod 9 is flattened and provided with anumber of perforations, which adapt it to permit the adjustment of theheight of the cut-ofl' arm and of the reel-support N, to which said armis pivoted.

It will be seen from the foregoing that all the devices for operatingthe platform and cut-off, except the foot-lever and the end of link q,connected thereto, are supported by the single adjustable reel-post, andthat the cut-ofl and platform, with the exception of the pivotal supportof the latter, are also supported by said post, and in such manner as tofreely allow the vertical or horizontal adjustment of the reel relativeto the cutters, while, also, the position of the platform and cut-offrelative to said cutters, and the extent of reel-guide standard, V,provided with guiding-pulleys v v to the reel-band, is connected, by alink or brace and coiled spring, W, with the lifting segment-lever X,or, if preferred, some fixed point on the main frame, and serves to keepthe reel-band taut under all the varyin g positions of the hinged finger-bar and main shoe relative to the main axle, and also serves topermit the adjustment of the reel-post or reel-shaft on said postwithout requiring a change of the driving-belt.

The connection of the yielding brace w adjustably with the lifting-leveris, however, preferred, as adapting the reel-belt to the varyingdistance between the reel-shaft and its driving-pulley on the main axleconsequent upon the raising or lowering of the cutters.

These, with other parts of the machine, are more fully set forth inother applications of even date herewith, and need not, therefore, befurther described here.

Having now described my invention, what I claim as new under thisapplication, and desire to secure by Letters Patent, is-

1. Mounting the rock-shaft, which supports the dropping ortilting-platform, and by means of which said platform and the cut-offare operated,upon the reel-post, substantially as described.

2. The adjustable bracket or bearer P, provided with bearings for therock-shaft p, in combination with the reel-post, as set forth.

3. The single overhung reel-post, carrying the devices for operating thedropping or tilting platform and cut-off, in combination with thestraddling standard L, substantially as described.

4. The treadle R, shaft 1), and adjustable links g g (1 for sustainingand operating the platform and cut-off, when arranged and operatingsubstantially as described.

5. The single pivoted reel-post, in combination with the archedstraddling standard L, arranged on the pivoted main shoe, in front ofthe inner drive-wheel, substantially as described. I
